The yamaha yfz450 has 45hp stock, the honda 450r has 55hp stock. Banshees have like 38 i'm pretty sure, but you can get some serious hp out of em. If you're a beginner basically, you can get really hurt on a banshee. They are basically uncontrolable, but that's why I like them. You gotta be good with tools, cuz banshees need some work every once in a while. Blasters are like minibikes compared to a banshee. I went from a blaster to banshee myself and I was only 13 when I switched, But I rode the Blaster for 3 years prior to that, and I had been riding 250r's and Banshees before too. I have been riding since I was 3, so if you don't have a lot of experience, go with something in the middle of a blaster and banshee, like a 400ex, or z400, or just go all the way and get the honda or yam,aha 450's.
